Crafted for consistency and high performance, the Maestro’s 6lb Substrate Bag provides a nutrient-rich foundation for robust mycelial growth.

The substrate is prepared in bulk using 30-gallon containers with screw-on lids. Coco coir, vermiculite, gypsum, and aged horse dung are thoroughly mixed in each container, then hydrated and brought to capacity. The mixture is pasteurized in the containers before undergoing a three-hour sterilization process in a pressure cooker, ensuring a clean and fertile substrate.

Each batch is packed into a double sealed mylar grow bag with a micron filter patch, ready for use in your cultivation system.

Ideal for both beginners and experienced growers.
